"Bad Data in Module" after changing basically nothing

So I just spent a bunch of time editing a module, tediously changing a bunch of At-Start Stacks one at a time, and I had them all updated at working great, did a New Game to verify that everything was in good shape, and then I just added one more At-Start Stack, and all of a sudden the whole thing is just gone. When I went back into New Game after that single minor change, all of a sudden it says “Bad Data in Module: Image Not Found” for every image in the module, even though I haven’t done anything with them. What the hell?

…I was able to fix it by reentering each image that was in the game (just for each one once, thankfully; I didn’t have to do it for every individual duplicate piece). I’d really love to know why that happened so I can make sure it doesn’t happen again.

Thus spake rookiebatman:

That’s not enough information for us to be able to help you. We’d need
an errorLog at least, and possibly the original module and step-by-step
instructions for how to reproduce the problem.

If you can reproduce the problem with a minimal test module, I’ll take
a look.
